PHILLIPS, or MEMPHIS, rnnnnssnnnssienon TO THE K-D' mm (30., or CINCINNATI, OHIO, A CORPORATION or OHIO TELEPHONE LIGHT Application filed. March 8, 1929.- Serial N0.'345,265.-

This invention relates to improvements in telephone lights and has especial relation to a light for attaching to telephones for the purpose of illuminating a memorandum pad or the dial ofwhat are known as dial telemade (c) To provide automatic means for turning on the light during use of the telephone; and

(cl) To generally improve the details of construction of such a device.

The means by which the foregoing and other objects are accomplished and the manner of their accomplishment will readily be understood from the following specification Lon reference to the accompanying drawings,

in which:

Fig. 1 is an elevation of a typical form of dial telephone showing my device applied thereto;

Fig. 2 is a sectional plan taken through the battery box of the device;

Fig. 3 is a fragmentary section taken on the line IIIIII of Fig. 1; I

Fig. i is a transverse section through the pad holder and the battery box showing the means by which the battery box is secured to the pad shelf;

Fig; 5 is a section taken on the line VV of Fig. 1 showing the clip for attaching the device to the telephone;

Fig. 6 is a section on the line VI-VI of Fig. 1 showing the manner of attaching the automatic contact to the telephone.

Referring now to the drawings in which the various parts are indicated by numerals;

10 is the base of the telephone and 11 the dial thereon, 12 is the stem, 13 the mouthpiece, 14 the receiver and 15 the receiver hook.

My device comprises a memorandum pad shelf 16 on which a memorandum pad 17 maybe disposed. Secured to and projecting from this shelf is a clip 18 by which the pad shelf may be detachably secured to the telephone stem. Disposed under the shelf 16 is a battery box 19 having an open top. This box is substantially U shaped in cross section with laterally projecting flanges 20 extending. outward from the upper edges thereof and which flanges are adapted to be held a ainst the underside of the shelf 16 by means 0 lugs 2l so that the box may be detachably engaged with the underside of the shelf by sliding the .box longitudinally. Disposed in the box are one or more dry cells 22, which, furnish current for the light, these cells being insulated from the box in usual manner, by the covering therearound.

Disposed in one end of the box 19 is an in sulating washer 23 on which is mounted a spring contact 24 which engagesin usual manner with one end of one of the cells. From this contact'24, an insulated wire 25 leads through a flexible tube 26 to the light'bulb 27 ,'with which it contacts. 28 is a reflector. The tube 26 is of the well known type which is deformable along its axis but which is selfsupporting and will stand in any position to whichit is moved, supporting the bulb 27 and reflector 28 mounted upon its free end in any adjusted position.

Disposed-in the opposite end of the box is aninsulating member 29 which is provided with a metal shoe 30, which shoe makes con-. tact with'the opposite end of the .dry cells. 31 is a sliding metal switch which is grounded tothe container 19-and is provided with .a button 32, by which it'may be laterally shifted to make contact with the shoe 30. The box 19 is grounded through'the tube 26 to the socket of the light 27 so that when the switch 31 is shifted and contact made with the shoe 3O thecircuit from the battery to the lamp is completed. a

In addition 'to the switch 31, there is provided anautomatically operableswitch. To the shoe there is secured a,wire33 insulated throughout its length which wire extends, and is secured to a clip 34- which is provided. witha laterally extending contact end 35. This clip is secured around the up- 1 through said bulb. p

2. The combination with a telephone,'of anelectric lamp, and means for automatically;

per end of the phone stem 12 by pushing the clip into engagement therewith. An insulating washer 36 prevents electrical contact between the stem and the clip. When in place the contact end 35 is disposed over the receiver hook 15 so that when the receiver is lifted from the hook, the hook will engage with the contact 35 and through the metallic parts of the telephone will complete a circuit for the light 27. It will be especially noted shelf to the stem of the telephone by meansof the clip provided, and in case the automatic switch is used to additionally secure that switch to the telephone in similar manner. hen thus in place the light bulb may be adjusted to throw light both on the. pad shelf and on the telephone dial, making itpossible to use either or both of these with out the necessity of other light. The light is also useful in reading names and numbers in the telephone book, and for this purpose of course the hand switch 31-32 is primarily useful. i 3

Having described my invention, what I claim is: l i v l. Illuminating means for a telephone, ha ving a receiver hook, automatically movable on removal of said receiver, said illuminating means comprising a battery box, means fordetachably securing said box to the telephone,

a flexible metal tube grounded toand-lead ing from said box, a bulb socket securedin the end of said tube and grounded thereto, a bulb in said socket, a battery cell disposed in and insulated from said boxyan insulated wire within said'tube connecting said bulb and a pole of said cell, an insulated member, having an integral contact disposedin the path of movement of said receiver hook, and

an insulated member connecting said contact member with the opposite pole of said'cell,

whereby on removal of thetelephone receiver said hook will ground said cell through said telephone parts and completed the circuit energizing said lamp upon the establishment of a talking circuit and deenergizingthe same upon normal breaking of such talking ciiw cuit, said'means comprising a contact inenj1- ber connected in the energizing circuit for said lamp and disposed in the path Of an element of said telephone automatically movable to establishor break a talking circuit, and a CHARLES C.
